Microspeed units differ from drives with speed stages and variable-speed drive systems. They are a combination of two or more brake motors linked by a mechanical gearbox. [The brake of the main motor is designed as a friction coupling, the brake of the creep speed motor acts either direct or via the gearbox of the complete drive.] A number of speeds or whole ranges of speeds can be achieved by using two speed, slip-ring or DC motors and even further microspeed motors.
Benefits
Large speed ratios of up to 500 : 1 are possible.
Precise stopping with creep speed motor for rapid positioning. High repeat positioning accuracy.
Higher switching frequency compared to two speed motors.
Creep speed constant and virtually independent of the load.
EG integral pulse generator
When the rotor rotates, two sensors trace a multi-pole magnet ring fixed to the rotor shaft. Depending on the application, the signals generated can be used to provide information and for monitoring and switching contacts by means of an evaluator unit.
